The kernel integration is computed by message passing on graph networks. This approach has substantial practical consequences which we will illustrate in the context of mappings between input data to partial differential equations (PDEs) and their solutions. In this context, such learned networks can ...

In this paper we propose a new convolution neural network architecture, defined directly into graph space. Convolution and pooling operators are defined in graph domain. We show its usability in a back-propagation context. Experimental results show that our model performance is at state of the art...
Graph embedding(GE)也叫做network embedding(NE)也叫做Graph representation learning(GRL),或者network representation learning(NRL),最近有篇文章把graph和network区分开来了,说graph一般表示抽象的图比如知识图谱,network表示实体构成的图例如社交网络, 我觉得有点过分区分了。图1.1是整个GE大家族,本文只介绍绿色的,蓝色...

introduced DeepONet, a novel network architecture that effectively approximates the solution operator of linear and nonlinear parametric PDEs. DeepONets have found applications in various fields of physics73,74, including hypersonics with the work of Mao et al.75, who approximated the fluid flow ev...
, n) represents the threshold values for each node in the ith layer, and f[ċ] is a nonlinear operator. The wi and bi are the parameters to be estimated. Equation (1) can be interpreted as a nonlinear function that represents the described n‐layer feedforward neural network. This ...
The “//” operator is integer division in Python. Before calling the program-defined accuracy function, the demo sets the network into eval mode. Technically, this isn’t necessary because train and eval modes only give different results if the network uses dropout or layer batch normalization...
